Further note: In Paul Stillwell's book "Battleship Arizona", on page 234, he writes "Members of the crew went over the side and swam to the Arizona's boats that were tied up to quays and booms." I think that pretty much answers it.
Also, in regards to Arizona's configuration on Dec. 7, besides the canvas 'tents', there are three other items to note:
1. On top of the foretop is a pedestal for an air-search-radar antenna that was to be installed. If you are using the Banner kit, it's missing. See this pic:
2. On the main deck level, there are two tubs (one port side, the other starboard) for 1.10"/75 antiaircraft quad machine guns. These guns were not installed as of Dec. 7, therefore the tubs were empty. The guns are included in the Banner kit.
3. The boat booms would of been extended with the boats being in the water. The Banner kit's instructions show the retracted.
If you have any other questions, please let me know.
